I do not really understand why we have to catch the exception and throw it.

try
{
   // code that may throw exception here 
}
catch(SQLException sqlex)
{
   //Handle this exception here 
   //Don't re-throw the exception.
   //Other exceptions will remain uncaught.
}

try
{
   // code that may throw exception here

catch(SQLException sqlex)

   //We really want to rethrow just that exception for some reason.
   throw;
}
catch
{
   //Whereas for everything else, we want to handle the exception here...
